Read mode
In this mode, the master reads the M41T11 slave after setting the slave address (see
Figure
address A
address are repeated, followed by the READ mode control bit (R/W = 1). At this point, the
master transmitter becomes the master receiver. The data byte which was addressed will be
transmitted and the master receiver will send an acknowledge bit to the slave transmitter
(see
The M41T11 slave transmitter will now place the data byte at address A
master receiver reads and acknowledges the new byte and the address pointer is
incremented to A
This cycle of reading consecutive addresses will continue until the master receiver sends a
STOP condition to the slave transmitter.
An alternate READ mode may also be implemented, whereby the master reads the M41T11
slave without first writing to the (volatile) address pointer. The first address that is read is the
last one stored in the pointer (see
